Segment Reporting [Abstract] |
Segment Information | Segment Information We maintain four reportable segments based on four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Within our four reportable segments, our core products and services are focused on the following markets: general industrial, chemical and petrochemical, oil, gas, power generation, commercial, food and beverage, rail and transit, and other, which we refer to as our "key end markets." We offer a full suite of products (heating units, electrode and gas-fired boilers, heating cables, industrial heating blankets and related products, temporary power solutions and tubing bundles), services (engineering, installation and maintenance services) and software (design optimization and wireless and network control systems) required to deliver comprehensive solutions to some of the world's largest and most complex projects. Our Chief Operating Decision Maker ("CODM") is our President and Chief Executive Officer. Our CODM uses the reported measure of segment profit or loss to assess segment performance and allocate resources to the segments informed by a strategic process to optimize value to our shareholders. We measure the profitability of our consolidated entity using "Segment profit." Segment profit is sales reviewed by the CODM, less cost of sales and selling, general, and administrative expenses, adjusted. For purposes of this note, sales and expenses reviewed by the CODM are attributed to segments on the basis of the business unit of record. Sales as stated on our consolidated statements of operations and comprehensive income is based on the legal entity of record. We transact business frequently between our legal entities through intercompany transactions. These transactions result in intersegment sales and costs recognized. We account for such transactions using our transfer pricing methodology and intercompany transactions are eliminated upon consolidation.

(1) - "Sales" are attributed to the reportable segment on the basis of the physical location and jurisdiction of organization of the subsidiary that invoices the material and services. The sales reviewed by the CODM are attributed based on the business unit which made the sale. The adjustments shown above represent these differences. Therefore, we have adjusted the sales reviewed by the CODM to reconcile such Sales. (2) - The significant expense categories and amounts align with the segment-level information that is regularly provided to the CODM. (3) - Selling, general, and administrative expenses, adjusted (non-GAAP), represents the Selling, general, and administrative expenses less depreciation expense, other unallocated enterprise expense, and impairment and other charges. (4) - Other unallocated enterprise expense includes miscellaneous corporate costs not allocated, such as stock-based compensation, miscellaneous gain/loss on sale of assets and other. The fiscal 2024 amounts include charges associated with the Russia Exit. We do not provide segment asset information to our CODM, and as such, we do not have a segment assets measure.
